The first housing 11a is formed with a first air outlet 19a at a position corresponding to an inner end of each first flow passage 13 a; the second housing 11b is formed with a second air outlet 19b corresponding to the second flow channel 13 b; the third housing 11c has a third outlet 19c formed corresponding to the third flow path 13 c. Preferably, the cross-sectional dimensions of the first, second and third flow channels 13a, 13b, 13c are gradually reduced along the flow direction of the gas flow.

In the illustrated embodiment, the first, second and third fans 20a, 20b and 20c are centrifugal fans, and the first, second and third air inlets 18a, 18b and 18c are disposed corresponding to the axial side ends of the first, second and third fans 20a, 20b and 20c and are located inside the bracket 10; the first, second and third outlets 19a, 19b and 19c are located on the upper side of the rack 10, the first outlet 19a faces the rear neck, and the second and third outlets 19b and 19c face the left and right surfaces. In the figure, the first, second and third air inlets 18a, 18b and 18c are formed by a plurality of small holes in a ring array shape; the first, second and third outlets 19a, 19b, 19c are formed by a plurality of strip-shaped holes arranged in a row. It should be understood that the air inlets 18a, 18b, 18c and the air outlets 19a, 19b, 19c may be any shape suitable for air inlet/outlet, and are not limited to the specific embodiment.

Preferably, as shown in fig. 3 and 4, a first inner shell 40a is disposed in each first flow channel 13a to accelerate the airflow of the first fan 20a to the first air outlet 19 a. The first inner casing 40a is substantially in a curved horn shape, one end of the first inner casing facing the first fan 20a is open, and the other end is closed, and an airflow outlet 42a facing the first air outlet 19a is formed on a side wall of the first inner casing 40 a. Preferably, the shape of the first inner casing 40a matches with the shape of the first flow channel 13a, and is disposed closely to the first outer casing 11a and the partition 12, and the airflow of the first blower 20a flows to the first air outlet 19a through the first inner casing 40a, that is, in the case where the first inner casing 40a is disposed, the inner space of the first inner casing 40a serves as the actual first flow channel 13a of the airflow of the first blower 20 a.

The inner wall surface of the first inner casing 40a may be designed accordingly as required, so that the flow channel in the first inner casing 40a meets the requirement for accelerating the airflow, as shown in the illustrated embodiment, a protrusion 44a is formed on the inner wall surface of the first inner casing 40a at a position corresponding to the airflow outlet 42a, so that the size of the cross section of the flow channel in the first inner casing 40a corresponding to the airflow outlet 42 a/the first air outlet 19a is smaller than that of other parts, and the airflow forms an air-squeezing acceleration effect when passing through the protrusion 44a, thereby increasing the flow velocity of the airflow flowing to the airflow outlet 42a or the first air outlet 19 a. Compared with the structure of forming a protrusion or the like on the inner wall surface of the first outer housing 11a to change the flow path structure, it is more convenient to form the first inner housing 40a on the support alone to obtain the required flow path structure. It should be understood that, in the case where the first inner casing 40a is not provided, a projection may be formed on an inner wall surface of the first outer casing 11a, that is, an inner wall surface of the first flow passage 13a, to change the flow passage structure.

As shown in fig. 3 and 5, a second inner casing 40b is provided in the second flow passage 13b, and the second inner casing 40b is in a triangular block shape and is disposed in close contact with the second outer casing 11b and the partition plate 12. Similarly, the second inner case 40b is open at one end toward the second fan 20b and closed at the other end. The inner space of the second inner case 40b serves as an actual second flow path 13b for the airflow of the second fan 20b, and an airflow outlet 42b facing the second air outlet 19b is formed on a side wall thereof. Preferably, the inner wall surface of the second inner casing 40b is formed with a protrusion 44b at a position corresponding to the airflow outlet 42b, so that the size of the cross section of the flow passage in the second inner casing 40b corresponding to the airflow outlet 42/the second air outlet 19b is smaller than that of the other portions, and the wind speed of the airflow flowing to the airflow outlet 42b is raised.

A third inner casing 40c is provided in the third flow path 13c, and the third inner casing 40c is in a triangular block shape and is disposed in close contact with the third outer casing 11c and the partition plate 12. Similarly, the third inner case 40c is open at one end toward the third fan 20c and closed at the other end. The inner space of the third inner case 40c serves as an actual third flow path 13c for the airflow of the third fan 20c, and an airflow outlet 42c facing the third outlet 19c is formed on the sidewall thereof. Preferably, a protrusion is formed on the inner wall surface of the third inner casing 40c at a position corresponding to the airflow outlet 42c, so that the size of the cross section of the flow channel in the third inner casing 40c corresponding to the airflow outlet 42 c/the third air outlet 19c is smaller than that of the other parts, and the wind speed of the airflow flowing to the third air outlet 19c is increased.

It should also be understood that, in the case where the second and third inner casings 40b, 40c are not provided, a protrusion may be formed on the inner wall surfaces of the second and third outer casings 11b, 11c, that is, the inner wall surfaces of the flow passages, to change the flow passage structure.

In the illustrated embodiment, the two first flow paths 13a in the first casing 11a are separated from each other by the connection of the partition 12 and the first casing 11a, and the airflows of the two first fans 20a do not affect each other. It should be understood that the air flow may be partitioned by the first inner casing 40a in the case where the first inner casing 40a is provided, and the partition plate 12 is mainly used for fixing the first inner casing 40a and may be omitted. In addition, a single first fan 20a may be disposed in the first casing 11a, and the position of the first fan 20a may be determined according to the internal structure of the first casing 11a, so as to ensure the air outlet volume of the first air outlet 19 a. Further, the partition 15 may not be provided between the first flow path 13a and the second and third flow paths 13b and 13c, and in this case, the first fan 20a may not be provided. When the first fan 20a is not provided, as long as the power of the second and third fans 20b, 20c is large enough, the airflow can reach the first housing 11a and be blown to the neck through the first air outlet 19a, and a comprehensive and comfortable blowing cooling effect is also formed.

The utility model discloses hang when neck fan operates, outside air is by air intake 18a, 18b, 18c get into corresponding runner 13a, 13b, 13c in, through fan 20a, 20b, 20c with higher speed behind the pressurization by corresponding air outlet 19a, 19b, 19c outwards blow off. Wherein, the air-out of first shell 11a directly blows to back neck, second shell 11b, the air-out of third shell 11c respectively blows left and right face, plays comprehensive, abundant cooling effect of blowing. Furthermore, by the arrangement of the partition board 12, a part of the space, namely the space occupied by the cavity 14, is isolated, and the airflow is concentrated in the flow channels 13a, 13b, 13c and does not spread to the whole internal space of the shells 11a, 11b, 11c, so that the air outlet of the air outlets 19a, 19b, 19c is more concentrated and the air outlet volume is larger. Furthermore, through the arrangement of the inner shells 40a, 40b, and 40c, the protrusions 44a and 44b have an effect of squeezing and accelerating air flow, so that the air outlet speed of the air outlets 19a, 19b, and 19c is higher, and the air volume is larger.

It should be noted that the present invention is not limited to the above embodiments, and other changes can be made by those skilled in the art according to the spirit of the present invention, and all the changes made according to the spirit of the present invention should be included in the scope of the present invention.
